What is the best electrical estimating software for commercial contractors in 2026?
Electrical estimating tools split into assembly-and-labor-unit systems (Accubid, McCormick), takeoff tools (PlanSwift, STACK, Bluebeam) and AI estimating (Skoper). Which is best depends on whether you want to build the bid or review one.
Electrical estimating tools split three ways: assembly-and-labor-unit systems such as Trimble Accubid and McCormick, takeoff tools such as PlanSwift, STACK and Bluebeam, and AI estimating such as Skoper. Which is best depends on whether you want to build the bid yourself or review one.
The short answer
If you price from NECA labor units and your own assemblies, Trimble Accubid or McCormick Electrical fit that workflow. If the slow part is reading a commercial electrical set and getting to a priced bid with a scope of work, Skoper returns a finished, priced estimate in about three minutes for you to review. That is AI estimating, not AI takeoff.
Electrical estimating software compared
Facts come from each vendor's own site (STACK and PlanSwift read 2026-10-12, McCormick and Trimble read 2026-10-22), except where a line says otherwise.
| Tool | What it is | Electrical-relevant facts | Output |
|---|---|---|---|
| Skoper | AI estimating | Reads plans and specs; every quantity names its source sheet; priced lines plus a scope of work; price edits are saved to your price book | Priced estimate, scope of work, Excel workbook with an Assumptions & Sources sheet |
| STACK | Cloud takeoff and estimating | AI auto-count of symbols; linear, area and volume measurement; assemblies; unlimited viewer seats | Takeoff and estimate |
| PlanSwift | Takeoff and estimating | Takeoff Boost: pick a symbol once and AI finds matches across the selected plans; assemblies with labor | Takeoff and estimate |
| Bluebeam Revu | PDF markup and measurement | Markup, counts and measurement on PDFs; keep it for RFIs and markups | Markups, measurement reports |
| Trimble Accubid Anywhere | Electrical estimating | Trimble's MEP page describes it as "estimating software for electrical & ICT contractors"; the product page itself was not reachable when we checked | Estimate |
| McCormick Electrical | Electrical estimating | Its own site: auto-count and "Auto Home Run" takeoff, a database of 25,000 prebuilt assemblies, its own labor units plus three levels of NECA labor units, pricing-service compatibility with major suppliers, bid proposals and material lists generated from the takeoff | Takeoff, estimate, proposal, material list |
| BuildVision AI, ScopeTakeoff, QuoteIQ | AI takeoff and estimating vendors | Each publishes its own "best electrical estimating software" roundup naming itself first; we read them for what they list, not their rankings | Varies |
| Excel | Spreadsheet | Manual assemblies; no automatic labor-unit tracking | Whatever you build |
How to choose: AI estimate, takeoff-only or spreadsheet
- Spreadsheet: works for small service jobs. A single panel can have 30+ line items under it, so it strains on commercial sets.
- Takeoff and assembly systems: you control every count and labor unit. Best when your labor database is the asset.
- AI estimating: the software counts devices and fixtures from the set, prices them and writes the scope; you check panel schedules, the biggest cost lines and exclusions.
Skoper's position: AI captures about 90% of what is on the plans, pricing swings about 10% either way, a person reviews every estimate, and hard-to-read plan sets cause most errors.
Test on a bid you already won: do device counts match, are lighting controls and low-voltage scope called out, and do your price changes persist?
FAQ
What is the best electrical estimating software?
For labor-unit-driven bids, Accubid or McCormick. For quantities from PDFs, PlanSwift or STACK. For a priced estimate and scope from the plan set, Skoper.
What is Skoper?
Skoper is AI construction estimating: upload a job, get a priced estimate and scope of work in about three minutes, then review it.
Can AI count electrical devices?
It captures about 90% of what is on the plans; you verify the rest.
Try it on a set you already bid
Upload an electrical scope from a past bid and compare device counts first, then prices.
